AWS Drift Auditor

Scans your AWS infrastructure and flags outdated patterns, over-provisioned resources, and cheaper modern alternatives.

Finance
The Gap

Teams unknowingly run AWS like it's 2018 — self-managed K8s clusters, EC2 for everything, legacy networking — wasting 30-80% on ops and cost when newer managed services exist.

Solution

Connect to an AWS account via read-only IAM role. The tool maps all resources, compares against current AWS best practices and service capabilities, and generates a prioritized report: 'Replace this self-managed K8s cluster with ECS Fargate to save ~$X/month and eliminate Y ops hours.' Continuously re-scans as AWS evolves.

Feasibility Scores
Pain Intensity7/10

Real pain but often invisible — teams don't know they're wasting money on outdated patterns because everything 'works.' The pain is diffuse (slow ops velocity + excess cost) rather than acute (system is down). Budget pressure and layoffs in 2024-2026 are making engineering leaders more cost-conscious, which helps. But this is a 'vitamin not painkiller' risk — teams can ignore this for years.

Market Size8/10

TAM is massive. ~1M+ companies use AWS, ~100K+ have meaningful spend ($10K+/mo). Mid-size teams (your target) number in tens of thousands. At $299-999/mo, even capturing 1,000 customers = $3.6-12M ARR. The adjacent cloud cost optimization market is $5B+ and growing. Architectural modernization advice specifically is underserved by tooling.

Willingness to Pay6/10

Mixed signals. Engineering teams are used to free AWS-native tools (Trusted Advisor, Cost Explorer). $299-999/mo is reasonable if you can show 10x ROI (save $3K-10K/mo), but proving that before they buy is the challenge. Enterprises will pay, but mid-size teams have tighter budgets and more 'we can do this ourselves' mentality. The free scan needs to show jaw-dropping savings to convert. Consulting firms charge $50K+ for this analysis, so there's willingness — but from tool? Less proven.

Technical Feasibility6/10

Read-only IAM scan and resource mapping is straightforward — AWS APIs are well-documented. The HARD part is the recommendation engine: mapping thousands of resource configurations to modernization advice requires deep, constantly-updated AWS expertise. You need to know that 'RDS MySQL 5.7 on m5.xlarge with these access patterns should be Aurora Serverless v2' — that's domain expertise encoded as rules/heuristics. An MVP with 10-15 high-value rules (EC2→Fargate, self-managed K8s→EKS/ECS, NAT Gateway optimization, GP2→GP3, etc.) is doable in 6-8 weeks for a strong AWS engineer. But the moat IS the rule quality, and keeping it current is ongoing work.

Competition Gap8/10

This is the strongest signal. Every existing tool optimizes WITHIN your current architecture (rightsizing, reserved instances, spot). NOBODY automates the question 'should you even be using this service/pattern at all?' AWS Well-Architected is a manual questionnaire. Consulting firms do this but charge $50-200K. There's a clear gap for an automated, opinionated modernization advisor. The closest thing is a senior AWS architect doing a manual review — you're productizing that.

Recurring Potential8/10

Strong recurring model. AWS releases 60+ new services/year, so recommendations need constant updating. Infrastructure drifts as teams add resources. Continuous monitoring catches new waste. Slack alerts and migration tracking are inherently ongoing. The 'your infrastructure is a living thing' narrative supports subscription well. Risk: if recommendations are too good, customers modernize and churn — but AWS sprawl means new waste always appears.

Strengths
  • +Clear gap in market: nobody automates architectural modernization advice — all competitors optimize within existing patterns, not across them
  • +Massive TAM with strong tailwinds: cloud cost pressure + AWS service proliferation + aging cloud infrastructure
  • +High-value free scan is a powerful acquisition channel — 'connect your AWS account, see how much you're wasting in 5 minutes' is a compelling hook
  • +Defensible moat via depth of recommendation rules — hard for competitors to bolt this on as a feature
  • +Natural expansion path: multi-account, multi-cloud, compliance, team workflows
Risks
  • !AWS could build this natively — they've been investing in migration tooling and Trusted Advisor. A single AWS re:Invent announcement could commoditize your core value prop.
  • !Rule quality is everything and is expensive to maintain — bad recommendations destroy trust instantly. One 'migrate to Fargate' suggestion that doesn't account for GPU workloads or specific networking needs = lost customer.
  • !Mid-size teams may prefer a one-time audit over continuous subscription — 'we ran the scan, got the report, now we'll fix things over 6 months' creates churn risk.
  • !Security-conscious teams will hesitate to grant read-only IAM access to a startup — enterprise sales motion may be needed for larger accounts, which is slower and harder as a solo founder.
  • !Quantifying savings accurately is critical but extremely hard — if you say 'save $5K/mo' and they save $500, credibility is gone.
Competition
AWS Trusted Advisor / AWS Well-Architected Tool

AWS-native tools that review workloads against best practices across cost, performance, security, and reliability pillars. Trusted Advisor flags underutilized resources; Well-Architected Tool runs structured reviews.

Pricing: Free with Business/Enterprise Support ($100+/mo for full checks
Gap: Generic recommendations, not opinionated about modernization paths (won't say 'replace EC2 with Fargate'). No dollar-amount savings estimates for architectural shifts. No migration playbooks. Well-Architected is a manual questionnaire, not an automated scanner. Neither proactively tells you 'your 2019 patterns are costing you $X/mo extra.'
Vantage (formerly CloudHealth alternative)

Cloud cost observability platform. Shows granular cost breakdowns, rightsizing recommendations, savings plans optimization, and cost anomaly detection across AWS, GCP, Azure.

Pricing: Free tier for small accounts. Paid starts ~$150/mo, scales with cloud spend (typically 0.5-1% of managed spend
Gap: Focuses on cost visibility and rightsizing, NOT architectural modernization. Won't tell you to replace self-managed K8s with ECS Fargate. Doesn't audit infrastructure patterns against current AWS best practices. No 'your architecture is outdated' analysis — just 'this instance is too big.'
Infracost + Cloud Posse / env0

Infracost shows cost estimates for Terraform changes pre-deployment. Cloud Posse provides reference architectures. env0 manages IaC workflows with cost guardrails.

Pricing: Infracost: Free OSS, Cloud tier $50-500/mo. env0: starts ~$250/mo.
Gap: Only works if you use Terraform/IaC — many legacy AWS setups are ClickOps. Doesn't audit existing running infrastructure for architectural debt. No 'you should modernize from X to Y' recommendations. Preventive, not diagnostic.
Datadog Cloud Cost Management / CloudHealth by VMware

Enterprise cloud cost management platforms. CloudHealth

Pricing: CloudHealth: Custom enterprise pricing, typically $10K+/yr. Datadog Cloud Cost: Included in some plans, otherwise usage-based.
Gap: Heavyweight enterprise tools — not built for mid-size teams. CloudHealth under Broadcom is losing innovation momentum. Neither provides architectural modernization advice. They optimize what you have, not challenge whether you should have it at all. Long sales cycles, complex setup.
Spot.io by NetApp (formerly Spot Instances) / Cast.ai

Automated cloud infrastructure optimization. Spot.io manages spot instances, rightsizing, and scaling. Cast.ai specifically optimizes Kubernetes costs by automating bin-packing and instance selection.

Pricing: Spot.io: percentage of savings (typically 25% of savings achieved
Gap: Optimizes within your current architecture, doesn't question the architecture itself. Cast.ai makes your K8s cheaper but won't say 'you shouldn't be running K8s at all, use Fargate.' Spot.io won't suggest Lambda instead of EC2. They're cost optimizers, not modernization advisors.
MVP Suggestion

Single AWS account scanner via read-only IAM role. Start with 10-15 high-impact, high-confidence rules: (1) EC2 instances that should be Fargate/Lambda, (2) self-managed K8s → EKS/ECS Fargate, (3) GP2 → GP3 EBS volumes, (4) old-gen instance types, (5) NAT Gateway cost optimization, (6) RDS → Aurora Serverless v2 candidates, (7) ElastiCache → DynamoDB DAX candidates, (8) Classic ELB → ALB migration, (9) unused/underutilized resources, (10) reserved instance vs savings plan optimization. Output: a beautiful, shareable PDF/web report with estimated savings per recommendation and difficulty rating (easy/medium/hard). No continuous monitoring in v1 — just one-time scans with re-scan capability.

Monetization Path

Free one-time scan (single account, summary report with top 5 findings) → $299/mo Pro (full report, all rules, re-scan weekly, Slack alerts, up to 3 accounts) → $999/mo Team (unlimited accounts, migration playbooks with step-by-step Terraform/CDK code, team dashboard, priority rule requests, Jira integration) → Enterprise custom pricing (SSO, compliance reports, dedicated rule development, SLA). Consider also a one-time audit report at $499-1999 for teams that won't subscribe.

Time to Revenue

8-12 weeks to first dollar. Weeks 1-4: build scanner + 10 core rules + report generation. Weeks 5-6: landing page, free scan flow, Stripe integration. Weeks 7-8: beta with 10-20 teams from AWS communities/Reddit/Twitter. Weeks 9-12: iterate on rule quality based on feedback, convert free users to paid. First paying customers likely from the free scan showing $5K+/mo in potential savings — the report sells itself.
